Tiny Query String

A tiny (2kb minified) JS library for reading & writing URL query strings.

Installation

NPM:

npm install tiny-query-string --save

Bower:

bower install tiny-query-string --save

Usage examples

const tinyQS = require('tiny-query-string');

tinyQS.get('foo', 'example.com?foo=bar&baz'); // 'bar'
tinyQS.get(['foo', 'baz'], 'example.com?foo=bar&baz'); // {'foo':'bar', 'baz':true}
tinyQS.get('example.com?foo=bar&baz', false); // {'foo':'bar', 'baz':true}

tinyQS.set('foo', 'bar', 'example.com?baz'); // 'example.com?baz&foo=bar'
tinyQS.set(['foo', 'bar'], 'example.com?baz'); // 'example.com?baz&foo&bar'
tinyQS.set({'foo':123, 'bar':'qux'}, 'example.com?baz'); // 'example.com?baz&foo=123&bar=qux'

tinyQS.remove('foo', 'example.com?foo=bar&baz'); // 'example.com?bar'
tinyQS.remove(['foo', 'bar'], 'example.com?foo&bar&baz'); // 'example.com?baz'
tinyQS.remove('example.com?foo=bar&baz', false); // 'example.com'

Documentation

Note: The text argument always defaults to window.location.search if left unspecified, or '' if window does not exist.

.get()

Alias for the .getOne(), .getMany() and .getAll() methods:

.getOne( name [, text] )

Parse a URL to match a single key name, and return the corresponding value as a string or Boolean.

• name (string): The key to search for.
• text (string) [optional]: The URL text to search in.

tinyQS.getOne('foo', 'example.com?foo=bar'); // 'bar'
tinyQS.getOne('foo', 'example.com?foo'); // true

.getMany( names [, text] )

Parse a URL to match an array of keys, and return the corresponding values in an object literal.

• names (array): The keys to search for.
• text (string) [optional]: The URL text to search in.

tinyQS.getMany(['foo', 'bar', 'baz'], 'example.com?foo=123&baz'); // { foo: '123', bar: false, baz: true }

.getAll( [text] )

Parse a URL and return all query-string values as an object.

Note: If using the .get() alias with a specific text argument, pass false as the second argument (e.g. tinyQS.get('example.com?foo', false)).

• text (string) [optional]: The URL text to search in.

tinyQS.getAll('example.com?foo=bar&baz'); // { foo: 'bar', baz: true }

.set()

Alias for the .setOne() and .setMany() methods:

.setOne( name, value, [, text] )

Add a single key (and its corresponding value) to the end of a URL.

• name (string): The key to add.
• value (string|Boolean|number): The corresponding value. If the value is a Boolean then only the key will be added.
• text (string) [optional]: The text URL to add the key/value to.

tinyQS.setOne('foo', 'bar', 'example.com'); // 'example.com?foo=bar'
tinyQS.setOne('foo', true, 'example.com'); // 'example.com?foo'

.setMany( values [, text] )

Add several keys to a URL.

• values (array|object): The keys to add. Accepts an array of valueless keys, or an object literal of key/value pairs.
• text (string) [optional]: The text URL to add the key/value to.

tinyQS.setMany(['foo', 'bar'], 'example.com'); // 'example.com?foo&bar'
tinyQS.setMany({foo: 'bar', baz: true}, 'example.com'); // 'example.com?foo=bar&baz'

.remove()

Alias for the .removeOne(), .removeMany() and .removeAll() methods:

.removeOne( name [, text] )

Remove a key from a URL query string, and return the updated URL.

• name (string): The key to remove.
• text (string) [optional]: The URL to parse and remove a key from.

tinyQS.removeOne('foo', 'example.com?foo=bar&baz'); // 'example.com?baz'

.removeMany( names [, text] )

Remove an array of keys from a URL query string, and return the updated URL.

• names (array): The keys to remove.
• text (string) [optional]: The URL to parse and remove keys from.

tinyQS.removeMany(['foo', 'bar'], 'example.com?foo=123&bar&baz'); // 'example.com?baz'

.removeAll( [text] )

Parse a URL and return all query-string values as an object.

Note: If using the .remove() alias with a specific text argument, pass false as the second argument (e.g. tinyQS.remove('example.com?foo', false)).

• text (string) [optional]: The URL text to search in.

tinyQS.removeAll('example.com?foo=bar&baz'); // 'example.com'
